A square with a side length of () has an area of 1 square decimeter. A square with an area of () has a side length of 1cm


A square with a side length of (1 decimeter) and an area of 1 square decimeter. A square with an area of (1 square centimeter) and a side length of 1 centimeter



A square has an area of 64 square decimeters. How many decimeters is the side length? How many centimeters is it?


A square has an area of 64 square decimeters and a side length of 8 decimeters or 80 centimeters



The area of a square with a side length of 1 cm accounts for () of 1 square decimeter
A. One tenth B. one hundredth C. one thousandth


One hundredth
One hundred square centimeters = one square decimeter



Is (a = x + +) & (b = x) an expression in C language
Define int x = 0, a, B; in the following options, the expression that makes a value 0 and b value 1 is______ A) A = x + +, B = a + + b) a = x + +, B = x + + C) (a = x + +) & (b = x) d) (b = x + 1) | (a = x) why and how to exclude the other three?


C is definitely wrong, because if a in front of a is 0, then B will not be executed after the short-circuit operation, so it can not be 1 D. similarly, if B in front of a is 1, then a will not be executed because of the short-circuit reason of logical operation. A assumes the execution time of + + operation (depends on the critical point defined by the compiler, which is not specified in C standard



The equivalent of X in the while (x) statement to the following conditional expression is () a.x! = 0 B.x=
In the while (x) statement, X is equivalent to ()
A.x!=0 B.x==1 C.x!=1 D.x==0


A. If the value in () is 0, it is false and if it is not 0, it is true



Divide the formula x = A-B by ab to form the form of X, a for B?


B = a divided by 1 + ax
You multiply AB first, and then use a = to represent one side of the equal sign. Finally, you extract the formula on the other side of the equal sign, and extract B! Finally, you can get x, a to represent B



The formula x = 1 / A-1 / B is changed to the known form of X, a and B


B = a divided by 1-ax
